VEHICLE-WHEEL.

I Specification of Letters Patent.V

Application led'anuary 21, 1916. Serial No. 73,322.

To all 't0/tom 'it may concern:

Be it known that Founnsr F. l'isrnluvraw, a eitizen or the United States, residing at Cleveland, in the county ol Cuyahoga and State oi Ohio, has 4inventa-ul certain new and useiul .lniproveuneiits in lVfchicle-l/Vheels, ot

which the :followingl is a sljieeificatioiu.

This invention relates to `vehicle wheels provided with means te give resiliency to the tread, all substantially as shown and described and particularly pointed out in the claim. n

In the accompanying drawings, Iiigure 'l is a side elevation `partly in section oli a wheel embodying the invention, and Fin'. il

a central cross section thereof.

As thus Shown the wheel comprises a 'practically two-part hub in which themain part or member a has a tubular extension 2 upon which the part or member is sleeved and locked in place by a cap nutn engaged upon the extremity of said: extension and servingr to clamp part o in place. Beth said parts have radial 'flanges 3 and it respectively', oi' proportioned width as shown, and

a transversely curved seat is provided in theY immediate hub oi both said parts which receive the inflatablel cushioning or resilient pneumatic tube d'. The inner peripheral portion oi said tube has a strip G 02E' sheet steel laid therein and adapted to come eena trally at its bearing on the curved seat 5 to. promote frictional engagement on said seat and also to reinforce the bearingr et' the tube at that point and toeover the joint7 and said tube is provided with a, valved nipple 7 as usual to inflate the same.

On its outer periphery the tube Z is provided at regular intervals with swells or enlargements 8 which alternate with other swells or enlargements 9 on the inside of the independent ring o, thus forming undulat ing' and interlocking surfaces which prevent possible slippinnr between said parts. The said rino; is confined between the flanpes 3 and l and has such width that it extends outward beyond the tube CZ at both sides in about the proportions shown, thus providinp; for more or less lateral expansion of the tube under the `weight or load carried by the wheel., and its undulating 'inner periphery with the humps 9 and scallops or depres# sions 10 alternating as shown and having the swells 8 of the tube coming in said depressions. The wheel is as effectually locked. in this otherwise irictional engagement ot' said parts as il they were in one piece. When inl-lated the tube d serves the saine purpose as the inner tube in the usual automobile tire so lar as resiliency in the wheel is concerned but with the material advantage, in this instance, oi very great reduction in size and initial cost and in the important iiaot that the tube is located where there is no possibility ci. puncture or `injury as in tires generally.

The spokes la may be ci any preferred pattern or style but are set lirmly in sockets or their equivalent in said ring, and have the'ielly l5 of the wheel mounted thereon as shown. Upon or about the telly or outer .rim oi. the wheel, I preferably employ a hard rubber tire 16 supported on a confining band 17, as shown.

In operation the weight comes upon the rubber tube through the ring o, and said ring'has a more or less limited play between the 4Hann-es 3 and flaccording to the load and the firmness of the tube.

What I claim is:

The construction of wheel described consisting' of a hub having a smooth circular transversely curved seat extending about the same and radially disposed flanges at the sides and apart :from said seat, in combination with a one piece ring carrying; the spokes of the wheel slidably mounted between said 'flanges and having alternate swells; and depressions about its inner periphery. and an inflatable rubber tube mounted on the curved seat on the hub and provided with alternate swells and depressions on. its outer periphery corresponding in number and position to the swells and depressions in said ring and in seating re lations therewith, the depth of the depressions in the rinp; beine; greater than the depth of the swells on the said tube, wher by expanding; space is afforded for the tube in service and the `resiliency thereof promoted.

In testimony whereof I ailix my signature in presenee ott' two witnesses.
